Re: Greg Garber(ESPN): "Petra Kvitova - the biggest disappointment"
Last year I expected that Kvitova would be very up and down with her grand slam performances, but instead she seems to have found consistency but lost the spark of brilliance that took her to Wimbledon/YEC titles last year.
I don't know if I'd say she's been disappointing exactly...two slam SFs, a QF and a fourth round are good results...
